0 phosphates is not good. May or may not be the issue... Though when I increased my nutrients my goni looked much better.

Other params seem fine.

Agree 0 phosphates is not good. Nitrates 37 should not have been a problem. That one spot looks bad. Damaged or something? Funny off color skeleton showing towards the bottom of it. Looks like an infection to me.

How is the lighting and flow? This coral likes a good amount of random flow, the polyps should be constantly waving.
